HAND OR BOOK REST.

SPECIFICATION forming part of Letters Patent No. 541,254, dated June 18,1895.

Application filed December 1, 1894- Serial No. 530,561. (No model.)

To aid whom it may concern:

Be it known that I, HEINRICH CHRISTIAN THIEMANN, residing at Hamburg,Germany, have invented new and useful Improvements in Hand or BookRests, of which the following is a specification.

This invention relates to a rest designed to afford a support for thehand of a person writing on the lower lines of a thick ledger or otherbook. The device is also adapted to be used as a support for holding abook in an approximately upright position while reading or copylllL'.

In the accompanyingdrawings, Figure 1 is a perspective view of myimproved rest, showing it in use as a hand-support. Fig.2 is a similarview with the plate a turned over. Fig. 3 is a perspective view of therest when constituting a book-support; and Fig. 4, a vertical section online at 4, Fig. 3.

The rest is composed essentially of two plates at, Z), arranged at rightangles to each other and connected by a triple hinge c. On that end ofthe plate I), which is connected to plate a, there is secured a smallerplate (1, which is of greater thickness than plate 19. The plate disprovided with a groove f, adapted to receive and hold the inner edge ct,of plate a. Within a bore of plate d, there is secured a catch h,surrounded by spring g, and provided with a folding finger i.

\Vhen the apparatus is to be used as a hand rest (Figs. 1 and 2), theplate I), is placed between the closed leaves of the book, while theplate a, may be folded either upon the left hand open leaf A (Fig. 1),or the right hand open leaf A (Fig. 2). Thus the plate a will form aconvenient rest for the hand.

When the apparatus is to be used as a book rest (Figs. 3 and 4), theplate b, is placed into a horizontal position and the plate a, is fittedwith its lower edge a into the groove f, of plate d. The book is placedupon plate I), and

against plate a, and is held in its open position by the finger i, whichis swung upward to bear against one of the open leaves.

What I claim is- 1. A book rest composed of two plates placed at rightangles to each other, and of a connecting triple hinge, substantially asspecified.

2. The combination in a book rest of plates a, b, with a connectinghinge c, a grooved plate cl, secured to plate b, and adapted to receivethe edge of plate a, a spring catch engaging plate d, and a foldingfinger secured to such catch, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
